一、核心选择标准

1. 光源类型  

   LED灯具为首选，优势包括：  

   高效节能：比传统光源节能50%-70%，减少长期能耗成本。  

   低热辐射：避免因灯具发热导致气流扰动和灰尘扬起。  

   长寿命：寿命可达5万小时以上，降低维护频率。  

   显色性与色温：推荐中性白光（4000-5000K），显色指数Ra≥80，确保精准识别颜色和细节。

2. 密封防尘设计  

   防护等级：需达到IP65及以上，防止灰尘、水汽侵入内部电路。  

   材质要求：外壳宜选用不锈钢、高纯度铝合金或阻燃PC材料，耐腐蚀且易清洁消毒。  

   结构设计：采用卡扣式密封或嵌入式安装，避免缝隙积尘。

3. 照度与均匀性  

   照度标准：根据洁净等级调整，例如ISO 5级（百级）需300-500 lux，ISO 6级（万级）不低于200 lux。  

   光线均匀性：均匀度需≥85%，避免局部过亮或阴影，可通过顶部主照明+工作台局部补光实现。

二、特殊功能需求                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      

1. 防爆性能  

   若车间存在易燃易爆气体或粉尘，需选择符合Exd IIB T6 Gb防爆标准的灯具，确保安全。  

   优先选择全密封防爆结构，避免内部电弧引发风险。

2. 应急照明功能  

   部分灯具可集成应急电源，主电源中断时自动切换备用电源，维持30分钟以上基础照明，保障人员安全撤离。

3. 智能化控制  

   支持调光、感应开关或联网控制，按实际需求调节亮度，进一步节能。

三、灯具类型推荐

1. LED洁净平板灯  

   超薄设计，表面光滑无死角，适合吊顶嵌入式安装。  

   可选防尘罩或亚克力扩散板，适配百级至十万级洁净车间。

2. 防爆型LED洁净灯  

   全密封结构，防爆认证+IP65防护，适用于化工厂、制药车间等特殊环境。  

   部分型号支持应急功能，满足双重安全需求。

3. 不锈钢支架灯  

   材质耐腐蚀，表面易清洁，适合高湿度或频繁消毒的车间。  

   支架结构便于维护时快速拆卸。

四、安装与维护要点

1. 安装方式  

   吸顶式：减少积尘面，适合层高有限的车间。  

   吊杆式：便于调整高度，优化光照覆盖范围。  

   嵌入式：与洁净室吊顶无缝结合，避免灰尘堆积。

2. 维护便捷性  

   灯具表面应光滑无缝隙，定期用酒精或无尘布擦拭。  

   选择模块化设计的灯具，便于快速更换损坏部件。

五、总结

无尘车间照明需以高密封性LED灯具为核心，结合洁净等级、防爆需求及智能化管理，选择符合以下条件的产品：  

IP65及以上防护等级；  

中性白光（4000-5000K）+高显色性；  

适配洁净室结构的安装方式（如嵌入式、不锈钢支架）。  

具体方案可参考行业通用标准（如ISO 14644），或咨询专业净化工程公司提供定制化设计。
